IMPROVEMENT 1N covERING THE ENDS or' RUBBER Hose.

The Schedule referred to in these Letters Patent and making part of the same.

To whom it may concern:

Be it known that we, J CHN P. RIDER and J AMns R. BIRD, both of Brooklyn, in the county of Kings, and State of N ewYork, haveinveuted certain new and usefullmprovements in vCovering and' Protecting the Ends of Vulcanized India-Rubber Hose; and we hereby declare the following to be a full, clear, and exact description of the same, reference being hadto the accompanying drawing, in which- Figure l is a view, `partly in section, of a portion of hose made in accordance with our invention.

4Iiiguref'is a longitudinal section of a modified form of the same. j

Figures Sand/1 are like sections of other modifications of the hose.

Our improvement is designedy not only to protect the ends of the' hose from all contact with moisture, thus avoiding the capillary action of the duck or canvas which entersinto the composition of the hose, but also to prevent the inner end of the metallic couplingshank, or that portion of the coupling-shank which is fitted insidethe hose,from wearing the inner rubber tube or lining of the hose; and to this end Oui invention consists'ot' a combined cap and pro tecting-tube, the cap being designed to it pver upon the exposed nds of the hose and keep them Afrom contact with moisture, and the protecting-tube forming in effect a continuation of the cap, and extending upon the inside ofthehose a sufficient distance back ofthe end to protect the inner rubberfhose lining, and

remove it from all contact with the metallic couplingshank. y y

The manner in which ourlinvention is or may be carriedA into effect will be readily `understood by refer .ence to the accompanying drawing.

In iig. 1 the covering and protecting device consists of a loose tube, a, of vulcanized rubber, which is made separate from, but soas to have the same diameter as the internal 'diameter' of the hose. One end of this tube is inserted4 in the hose, so as to extend therein the length of thecoupliug-shank; and the portion of the tube which' still projects from the hose is turned inside out over the end of the hose, and upon the outside of thesame,where it may be coniincd in place by rubber cement, or by the band, wire, or other device employed to fasten the coupling to the hose; or the tube may be first fitted upon the outside of the hose, and the projecting portion may be tucked in.

In applying the coupling b, its shank is inserted in the hose, which is protected by the inner portion of the tube a, so as to be entirely removed from-contact with the coupling. y

The tubea is bound and held tirmly in place upon tached to the end of the hose.

the inside by the coupling-shank, and upon the out side by the band c, or other suitable means;and thus the ends of the hose are fully protected,as well also as the inner hose-lining.

Instead of using a loose tube, as .j ust described, we

can accomplish the same results in the manner shown in fig. 2, by extending the rubber coating of the h'ose (ll, or by attaching a tube, d2., of thin rubber tothe end ot' the rubber coating before vulcanzation, thus producing a projecting tube which would in reality' sul'ts'is, to employ a loose tube of the proper length made in but not attached to the inside of the hose, and then brought over the end and attached only to the outside of the hose before vulcanization.

lhis moditication is shown in tig. 4, where `e isthe protecting-tube` placed inside the hose, buty not attached to the inner lining, and then turned over the end and upon the outside of the hose before the vulcanization of the same, so that it may be attached by the vulcanizing process. others, extends inside the hose4 the full length of the coupling-shank jl Another method of arranging the protecting-tube is shown in iig.` 3.' In this instance the tube y is vulcanized in such form vand shape as to cover, but not be attached to the end of the hose. by shaping the end g of the tube nearest the hose so that it shall extend over the face of, but not be at- Theend g is then attached to the hose-coating, and the remaining portion of the tube is formed upon the mandrel in the usual manner. 'lhetubel then forms part of the hose, and as it is shaped and applied tothe hose before vulcanizaton, a paper or other suitable dat ring, or soapstone, or any other disk is interposed between the part g and the end of the hose, so as to prevent the two from sticking together.' After the vulcaniziug, 'the lpaper ring, soapstone, &c., can be removed or torn away. l

, Other methods of combining the tube with thehose may be employed; as, for instance, the tube may be attached to the inside instead of the outside of the hose.v But we have here described those which we Ahave found by careful experiment and trial to be the most practicable. v

AIn all instances, it will be noticed that the tube is made and combined with the hose in suchmanner as to permit the endlof the hose being exlposed to view The tube in this case, as in This is effected and inspected whenever it is desired to ascertain the quality of thehose and the number of plies of duck or canvas which enter into its composition.

Having now described our invention, and the manner in which the same is or may be carried into eect,

What we claim, and desire to secure by Letters Patent, is-

1. The combination, with the ends of vulcanized India-rubber hose, of an elastic and water proof tube applied to the same, so as to cover the end and extend inside the hose the full length of the coupling-shank, substantially as shown and set forth.. l

2. As a new manufacture, vulcanized Iudiafrnbbcr hose provided at the end with a vulcanized rubber tube, arranged so as to cover the end and extend upon y the inside of the hose far'enough to remove the hoselining from contact'with the coupling-shank, substantially as shown and set forth.

3.A Hose composed of canvas or equivalent material and rubber, provided with a tube making part of the same', and vulcanizedin such' form and shape as to cov'er but notbe attached to the end of the hose, suby stantially as shown and set forth.

In testimony whereof, we have signed our names to this specification before two subscribing witnesses.
